[Means for Solving the Problems]

The present invention is intended to solve these disadvantages, and the gist thereof is a mechanism capable of moving and guiding a mounting member in two directions orthogonal to each other. A moving shaft is provided on the support member so as to be movable in one direction of movement of the mounting member, and a shaft moving mechanism for reciprocating the moving shaft is provided. Provided so as not to move in one direction, the connecting member is provided with a connecting shaft swingable in the other moving direction of the mounting member and immovable in one moving direction, and the connecting shaft is slidably inserted into the connecting member. A moving mechanism that allows the mounting member to move in one moving direction and pushes the mounting member in the other moving direction, and allows the mounting member to move in one moving direction Return the mounting member to the other moving direction when the In two orthogonal direction moving mechanism, characterized in that a Mododo mechanism for.

[Action]

When the moving shaft reciprocates by the shaft moving mechanism, the moving force is transmitted to the mounting member via the connecting member and the connecting shaft, and the moving shaft reciprocates in one moving direction, at which time the mounting member is pushed in the other moving direction. The moving mechanism for moving and the returning mechanism for returning in the other moving direction enable the mounting member to move in one moving direction, and when the moving mechanism pushes the mounting member in the other moving direction and the returning mechanism. When the mounting member returns to the other moving direction by the, the connecting shaft swings in the other moving direction of the mounting member and slides on the connecting member to allow the mounting member to move in the other moving direction.
